10 reasons why Mamata Banerjee lost and TMC failed to see the writing on the wall
The Statesman | 6 May 2026
Mamata Banerjee’s defeat in Bhabanipur was not the only shock for the Trinamool Congress. The bigger story was the scale of the collapse around her, with 22 of the 35 TMC ministers who contested the 2026 West Bengal Assembly elections losing their seats.
The result suggests that the verdict was not limited to anger against a few candidates. With the BJP crossing the 200-seat mark and the TMC falling to around 80 seats, Bengal has delivered a mandate that signals fatigue with the ruling establishment, a sharp BJP consolidation and, crucially, a failure by the TMC to recognise early warning signs on the ground.
1. Fifteen years of power caught up
Mamata Banerjee herself rode anti-incumbency to power in 2011. After 15 years in office, the same cycle appears to have turned against her. Voter fatigue with familiar faces, local networks and recurring complaints built up over time and eventually translated into votes.
2. Cabinet collapse reflected a wider loss of trust
When 63 per cent of ministers lose, it’s not just about individual defeats. It shows voters had lost faith in the government across departments, from education and housing to transport and welfare.
3. Bhabanipur defeat changed the perception
Banerjee losing Bhabanipur to Suvendu Adhikari by 15,105 votes changed how she was seen, from a leader many thought was unbeatable to one who lost in her own backyard.
4. BJP turned a narrow vote gap into a sweep
The BJP’s vote share of 45.84 per cent against TMC’s 40.80 per cent does not explain the seat gap on its own. What made the difference was how effectively those votes were spread across constituencies, turning small leads into decisive wins.
5. The rejection cut across Bengal
Losses of senior leaders such as Aroop Biswas, Bratya Basu, Chandrima Bhattacharya and Shashi Panja showed that this was not a localised shift. There was a shift on the ground across regions and voter groups.
6. Big defeat margins signalled decisive anger
From Goghat to Durgapur Purba and Dum Dum Uttar, several losses came with margins running into tens of thousands. These were not close contests but clear verdicts.
7. Welfare model met its limits
Mamata Banerjee’s politics was built around welfare delivery, such as cash support, subsidised food and targeted schemes. While that base remained, the results suggest welfare alone was not enough to hold together a broader electorate facing multiple local grievances.
8. Controversies dented key voter groups
The RG Kar case and the recruitment scam never really went away. Women and younger voters kept talking about them, and by the time campaigning got underway, the anger had settled into something quieter but harder to shake. People were simply asking whether those in power could be trusted.
9. BJP became the main alternative
With Congress and CPI(M) no longer serious players, voters who wanted the TMC out had essentially one place to go – the BJP. The anti-incumbent vote largely moved in its favour across constituencies.
10. TMC retained votes, but lost broader trust
Despite securing over 40 per cent vote share, TMC fell far behind in seats. The party held on to its loyalists, but winning over anyone beyond that circle proved difficult.
As per Election Commission data, the Bharatiya Janata Party has won 207 seats, while the All India Trinamool Congress has been reduced to 80. Congress and AJUP have two seats each, while CPI(M) and AISF have one each.
The result marks the end of a long phase of political dominance by Mamata Banerjee and gives the BJP its biggest breakthrough in eastern India.
The verdict also suggests that the signals of discontent were visible well before the counting day. The challenge for the TMC now is not just to explain the defeat but to rebuild a political organisation that failed to act on those signals in time.
